The deadline comes 60 days after the first sitting of the 450-seat parliament, which although elected in March has been in limbo as one coalition needed to form a government collapsed to make way for a rival alliance in the midst of accusations of treachery, bribery and fighting in the chamber.
However, Yevheniy Kushnarev, a senior member of the new coalition leader, the Party of Regions, said the dissolution of the Supreme Rada was unlikely.
"The 60-day timeframe set for the formation of the Cabinet of Ministers should be counted since the dismissal of the previous government," he said. "But there was no dismissal - the government just relinquished its powers before parliament, which are completely different things."
The parliamentary majority led by the pro-Russian Party of Regions nominated its 56-year-old leader Viktor Yanukovych as prime minister last Tuesday, but President Viktor Yushchenko has been hesitant to approve the nomination of his former rival in the 2004 presidential elections.
But with his former ally and first premier Yulia Tymoshenko leading the charge for a dissolution of parliament, Yushchenko also seems reluctant to disband the legislature and hold new elections.
Tymoshenko, the darling of the 2004 "orange revolution" that brought Yushchenko to power and previous premier-in-waiting in the first post-election coalition, formally withdrew from the Rada Monday with her eponymous faction in a bid to block the rival coalition's way to power. Her West-leaning bloc holds 125 seats.
On Monday, 244 members supported a resolution stating that if the president launched consultations on dissolving parliament, the Rada should immediately hold a plenary session "to maintain constitutional law and order in Ukraine."
